PROBLEM TO BE SOLVED: To achieve a compact performance device having simple structure in a game machine including the performance device capable of constructing an annular performance form.SOLUTION: A game machine includes a performance device 1a capable of constructing an annular performance form 1r in that a plurality of arcuate division parts are combined. The game machine 1 is configured such that the performance device 1a constructs at least one portion of the annular performance form 1r by changing to a second state, where a first division part 11 and a second division part 12 are displaced in a direction separating each other from a first state, where the first division part 11 and the second division part 12, namely at least one portion of the plurality of division parts, are overlapped while being adjacent each other. |
